I don't think proselytizing is necessary anymore; we've got enough folks on here now to get a sustainable community going, other people gradually finding their way over here over the next year or two (much as it happened with digg) is much better than a crazy server-destroying / spam-proliferating rush.

Reddit was perfectly enjoyable a decade ago with 10% as many users, we don't need very many of them to be able to offer a worthy reddit replacement to anybody who seeks one. (plus I suspect within 6 months or so we'll have way better apps than reddit does)
